To all whom itcmay concern:

Be it known that I, HARRY B. Karin, a subject of the Czar of Russia, and resident of New York city, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Electric-Circuit- Oontrolling Systems, of which the following is a specification.

The primary object of this invention is to enable a person to throw into and out of circuit or operation at will-at a distant point or points one or'moi'e electrical translating devices, such as arc-lights, motors, incandescent lights, etc; another object is to. provide means which will require compara tively little attention during long periods of time, for throwing into and out of operation such translating device or devices; other objects will appear hereinafter.-

The invention comprises novel improvements and combinations of devices hereinafter described and more particularly pointed out in the appended claims.

The invention is embodied in the apparatus illustrated in the accompanying drawview; Fig. 2 is a side elevation of a motor ings, forming part hereof, in which- Figure 1 is a diagrammatic 1llustrat1ve for controlling .the switch of the translating device; Fig. 3 is a front elevation of said motor, partly in section; Fig. 4. is a plan view; Fig. 5 is a central sectional view of 'the switch shown in Fig. 4, and Figs, 6, 7,

8 and 9 age detail views of parts of the switch.

The diagram, Fig. 1, shows a generator 2, mains 3, and a switch 1, of any usual or desirable type or construction. In the'particular instance illustrated, the mains 3 are connected bywires 5 with are lights 6, but it is obvious that other forms of translating devices may be substituted for the lights shown, and the main line circuits otherwise ing the nut 16 from being turned turning on and oil of current in circuit 8 by closing the switch at 10 either turns on or 0d the current from the circuit 3 to the translating devices. That is, successive clo- M,- sures and openings of the switch 10 causes alternate operations in the sw'tch boxes at one time connecting the translating de vices with the source 2 of electrical energy, and the next time disconnecting the said devices from said source 2, and so on in altcrnation. 1t is obvious that the translating devices may be divided into two or more groups, and that each of said groups may have its own circuit 8 and circuit closer 10, whereby such groups may be connected to and be disconnected from the generator any order of succession, thereby increasing or decreasing gradually the loads on said generator. It is also bbvious that the nurn- 32 her of translating devices in a group may vary from one to any convenient number.

The specific means shown in the drawi; for connecting and disconnecting tra' lating devices'to and frbm the mains now be described.

S designates a switch, which, in the in stance illustrated, is of the snap-switch type, (see Figs. 3, a and This St has a base 11 of insulating material, b: a central metal bearing 12 for the shaft The said shaft 13 is provided with a quick thread 14 and a head 15. Engaging with thread 14: is a nut 16, and the opposing faces of bearing 12 and nut 16 are toothed. at 17, 18 to form a loclcdevice for ven in. hearing 12 being fast to base 11, as will be understood) except as hereinafter set forth. The nut 16 is polygonal in horizontal section. or is otherwise arranged to have attached thereto the blades 19, 20 of the switch. These bla cs 19, 20 are insulated from each.

-other and are arranged to bridge the terminals 21, 22' on different levels of branch lines, or negative and positive conductors, such as 5, connected with the mains 3. Bit its lower end (Fig. 5) shaft 13 has attached or connected to it a sleeve 23, which s shaped internally to fit on the pol head 24- of a shaft 25 of the moto The not 16 is allowed a limited 1 shaft 13 bythe loch-sleeve l 27, such limited motion being for the nu pose; of allowing the thread hito lift teeth 18 out of mesh with the teeth 1?, e nut lti sliding' in the blades 19, 2t) at sucn times. The sleeve 26 has a pin 28 thereon to receive one end of a spring 29 whose other end is hooked on a pin. on the inside of the drum 30. Said drum 30 is provided with a handle 31 by which it is turned to Wind said spring 29, and the spring is prevented from unwinding by means of a suitable pawl and ratchet device 32. The shaft 25 is driven, in the instance illustrated,by a spring 33 and clock-gearing 34L The springs 39 and 33 may be, and preterably are, of such lengths and the constructions ot the gear of said mechanical motor and switch of such numbers, that, when fully Wound up, they Will operate the parts driven. by them for a great number of times, for SE'VQiiLi months, or a year or more, in the case of street lighting systems.

Primary and secondary locking devices or v detcnts are provided for the purpose'of cansing shaft 25 to be operated only as and when des red, and detents suitable to the purpose, with operating means therefor, will now he described. The priinery or normal lockdevice shown comprises a pin 35 on eat 36 and a coacting dog 3! on a lever 38, 'ch tulcrunied at 39, and which is pro ;ed with toe so for co-action with an ari'natnre lever The lever 4.1 is tulcrun' ed at 4:2 and is actuated by an electromag-net t3 in circuit 8, or a branch 9 there- The gear 36 is connected with a gear the t in by gearing 4:45. In the normal positions'ot the parts, the dog 3'? is in gement with gain 35' and locks the train inst motion, The auxiliary or seeecl: ordetent comprises pin on disk 4-6 and a dog t? which is out oit'the circular path of said 13in flis carried by an extension .e armature lever t]. The disk at connected 0' gear 4:8 with gear'SG. ihe pin 45 is so with relation to the pin 1-35 and docs 3' and that pin 4t?) will not Le sire "ed the operation of the device as hereinafter forth "until the pin 35 shali have moved so far to be ciear of dog 37 on the deenergiaing of magnet e3.

in order to allow the mechanism a proper terval. in. which to rotate shaft 25 and nut '16 from hearing 12, after es sever it, the dog 37 is held sition in which it coacts "with I anyconvenient means as, for in- 19 having one or more notches in its periphery to receive a 51 on the side iever 38. its long as lug 51 bears on .r: i if ra the circu ar nefi her of dish do 37 is 1 p i- J v 1' held out or the path or pm do, but when a notch T0 comes opposi drops (or is spring-moved in 35 an te log 51, the dog 37 into the path of v d stops the ihechanism.

The operation of the above described devices is follows: When it,is desired to start or'ste c the translating device {or do l 1 l l x l l l tates shaft 2 vices) operated by the switch for that energizing magnet t causing it to &1, thereby gaging lug; 51 from pin While si dog 4;: in to the path spring d crate; as long as the the parts renialn as is true of the notch 50 3) 0t attract its armature aand lever operating from not trims the gcari arrested by dog 47, the tra just d understood that the pin from the position it cc gagement with the dog particular circuit 8. ircuit is closed, thus that circuit and ing circuit 8, the magnet L3 the lever 41., which is thus causing periphery of sniping 33 d1"! to run down thread n giug to ride the disk 49, and thereupon the train 34: ans thus re- 5 in the direct caiise the nut 16 to move away whereupon. spring switch blades it or 111 the direction necessary dis, or is moved to its non Inal position by the dog t7, and allowi ssure of pin 4.5 on t? to release pin against the ion to "ti'cin the are disengaged. 29 rotates bearing; 12 until teeth 18 from teeth 1? sleeve 26 and cause not whereby the tee'h ne set to another et of kerfs or notches between the teeth 1'3.
